Application filed June 19,

lhis invention pertains to an adjustable mounting for an automobilelamp, and part cularly ith respect to a side lamp. The principal featureof the invention resides in the provision of two spaced sphericalmembers for providing a sock t in which the corresponding lamp mountingis adapted to seat so as to be capable of universal movement withrespect thereto for adjusting the posltion of the lamp, said membersbeing so spaced apart and formed as to permit of a certaln amount offlexibility or yielding as well as distortion for permitting the lamp tobe securely clamped in adjusted position.

Another feature of the invention resides in the formation of the lampsocket, the spherical seating portion and the screw-threaded bolt-likeprojection and wire conduit being formed in a single integral piece forsimplifying and stabilizing the construction.

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims.

Fig. 1 is a central vertical section taken through the lamp with itsmounting. Fig. 2 is a section taken on a line 2'2 of Fig. 1. Fig. 3 is acentral vertical section through a lamp mounting showing a modified formthereof. Fig. 1 is the same as Fig. 3 showing a second modified form.

In the drawingsthere is shown a lamp structure having a casing 10 intowhich the lamp socket 11 extends forsupporting a lamp bulb 12. The lampis adapted to be mounted in adjusted position on a body of anautomobile, and particularly the cowl which forms a support 13, saidsupport having an aperture formed therein through which the mountingextends.

Ciamped against the under side of the support 13 and about the openingtherein there is provided a spherically surfaced spacing shell 1 1provided with an elongated opening therein and having a radiallyextending flange 15 adapted to engage the surface of the sup port 13surrounding the opening. Mounted above said shell and spaced therefromthere is a second or upper spherical shell 16 having a sphericalcurvature conforming to that of the shell 14 and having the radiallyextending flanges 17 adapted to engage the upper surface of the support13 about the opening. The shell 16 is likewise provided with anelongated slot, and both of said shells are formed with correspondingconcave-convex 1926. Serial No. 117,686.

seating surfaces having substantially the same center of curvature. I

The lamp casing 10 is provided at its bottom with an upwardly extendingflange 18 which embraces and is rigidly secured to the corresponding incurvature to the concave surface of the upper shell 16 so as to seatsnugly therein. The socket 11 is provided with a hollow screw-threadedtubular stem 20 continuing from and formed integral with the seatingsurface 19 so as to project through the elongated opening in both of theseating shells 16 and 1 1.

Mounted over the stem 20 so as to engage the under-convex surface of theshell 1-1 there is a washer 21 provided with a flared end so formed asto overlap theelongated opening in the shell 14, engaging and conformingto the curvature of the surface thereof. The nut 22 is screwed onto thestem 20 so as to engage the washer 21 and clamp said shells 1d and 16intermediate said washer and the seating portion 19 of tee socket. Itwill be noted that the wire'connection 23 may extend up wardly into thelamp socket tl'irough the 1101- low stem 20 which formsa conduittherefor. From the above it will be observed that the lamp may beadjusted with respect to the sup porting member 13 by causing thespherical surfaces of the socket 19 andwvaslier 21 to sitioned entirelywithin the lamp casing while the spherical base portion 119 is mountedwith respect thereto separately of the socket. Furthermore the hollowscrewthreaded stem 120 is provided with a head 121 which engages thelamp socket or the lower portion of the casing for securing the lamp inthe casing. In other words, in this face'of the other shell, wherebysaid shells modified form, these three units are formed and assembledseparately, whereas in Fig. 1 they comprise a single unit formedintegral.

In the modified form shown in Fig. l, the lamp socket and hollow stem 20as well as the seating surface 19 thereof are formed in the same manneras shown in Fig. 1. For adjustably supporting the lamp, a bracket member216 is secured to the exterior surface of the casing and is providedwith a spherical seating shell 217 conforming to the spherical portion19 of the socket in which the latter is adapted to fit. The shell 2-17is provided with an elongated slot through which the stem 20 extends,and is supported upon the spacing washer 214 having a flar d periphery215 upon which the shell 21 re in this structurc, when the nut 22 isscrewed it, it clamps the shell 21? which is secured to the casingbetween the spherical socket portion 19 and the flared edges of thewasher 21%: whereby the lamp casing will be held rigidly in adjustedposition.

The invention claimed is: r

1. A lamp comprising a casing, a lamp socket extending therethrough andhaving a rounded surface formed thereon exteriorly of said casing, atubular stem continuing from said socket, a support for said lamp, apair of shells spaced apart and secured to said sup port, said shellshaving rounded surfaces sub stantially corresponding to the roundedsurface of said socket and provided with an opening through which saidstem may extend, a washer having a flared portion engaging the convexsurface of one of said shells, and means for tightening said washerthereagainst and drawing the rounded surface of the socket against therounded surface of the other shell for securing said lamp in adjustedposition.

2. A lamp comprising a casing, a lamp socket extending therethrough andhaving a spherical surface formed thereon exteriorly of said casing, atubular screw-threaded stem continuing from said socket, a support forsaid lamp, a pair of shells spaced apart and secured to said support,said shells having spherical surfaces substantially corresponding to thespherical surface of said socket, a washer having a flared portionadapted to engage the convex surface of one of said shells, and a nutadapted to screw on said store in en gagement with said washer fordrawing the spherical surface of said socket into clamping engagementwith the concave spherical surwill be drawn toward each other andclamped in distorted position for retaining said lamp in adjustedposition.

3. A lamp comprising a casing, a lamp socket mounted therein, a roundedportion formed below said socket and casing, a pair of shells spacedaparthaving rounded surfaces substantially corresponding to saidportion, and means for engaging and distorting one of said shells anddrawing said rounded portion into seating engagement with the othershell whereby said shells will be clamped together for retaining saidlamp in adjusted position.

4. A lamp comprising a casing, a lamp socket mounted therein, a roundedportion formed below said socket and casing, a support for said lamp anda pair of shells spaced apart having corresponding rounded surfacesconforming substantially to said rounded portion whereby said lattersurface mayseat in one of said shells and be adjustable with respectthereto,'and means for clamping said lamp to the other shell wherebysaid rounded surfaces will be drawn together and slightly distorted forretaining said lamp in adjusted position. v

5. A lamp comprising a casing, a lamp socket mounted therein, a roundedportion formed below said socket and easing, a support for said lamp anda pair of shells spaced aparthaving corresponding rounded surfacesconforming substantially to said rounded portion whereby said roundedportion may seat in one of said shells and be adjustable with respectthereto, a hollow threaded stem below said casing and extending throughsaid spherical surfaces and capable of adjustable mevement with respectto said shells, a flared washer mounted on said stem and engaging one ofsaid shells, and a nut adapted to screw thereon for engagement with saidwasher and drawing said rounded portion against the surface of the othershell whereby said rounded surfaces will be drawn together and saidshells distorted for clamping said lamp in adjusted position. r

6. A lamp comprising a casing, a lamp socket extending therethrough andhaving a rounded surface formed thereon exteriorly of said casing,'atubular stem continuing from said socket, a shell'havinga roundedsurface substantially conforming to the surface of said socket, a secondshell spaced apart from said first mentioned shell, and means mounted onsaid stem for engaging and distorting the second shell and clamping saidsocket against the first shell for securing said lamp in adjustedposition. 7

In witness whereof, I have hereunto afixed my signature.
